A strongly connected graph is a directed graph in which every pair of vertices is mutually reachable. This means that for any two vertices u and v, there is a directed path from u to v and a directed path from v to u.
Conditions: The graph is directed.; The criterion requires mutual reachability between every pair of vertices.

A connected graph is an undirected graph in which there exists a path between every pair of vertices. If even one pair of vertices is not connected by a path, the graph is called disconnected.
Conditions: The graph is undirected.; The criterion for judgment is whether a path exists between any two vertices.
